1.2 DEFINITIONS

1.2.1 As-Built Drawings

As-built drawings are the marked-up drawings, maintained by the Contractor on-site, that depict actual conditions and deviations from the Contract Documents. These deviations and additions may result from coordination required by, but not limited to: contract modifications; official responses to submitted Requests for Information (RFI's); direction from the Contracting Officer; design that is the responsibility of the Contractor, and differing site conditions. Maintain the as-builts throughout construction as red-lined hard copies on site and red-lined PDF files . These files serve as the basis for the creation of the record drawings.

1.2.2 Record Drawings

The record drawings are the final compilation of actual conditions reflected in the as-built drawings.

1.3 SOURCE DRAWING FILES

Request the full set of electronic drawings, in the source format, for Record Drawing preparation, after award and at least 30 days prior to required use.

1.3.1 Terms and Conditions

1.4.2 Concrete Floating Breakwater Loading

1.4.2.1 Wave Loading - Installed Position

The floating breakwater shall be designed for all wave loadings up to and including a wave train with significant wave (Hs) = 5.6 feet with a maximum period of 3.2 seconds (100-year return period). This wave may impact the floating breakwater from any angle including the direction of wave propagation perpendicular to the length of the concrete floating breakwater. AM004... The 100-year return significant wave approaching the Main Attenuator at 64 degrees from perpendicular and the Entrance Attenuator at 30 degrees from perpendicular be attenuated to a significant wave height of 1 ft. or less directly behind the attenuators ... AM004 The minimum design load from this wave shall be taken as 680 pounds per linear foot (plf) of breakwater length for the main breakwater and 2150 lb/lf for the entrance breakwater. This full load shall be used in combination with the transient mooring wind load indicated below. AM004... In addition, the concrete floating breakwater shall be designed for a wave train with significant wave (Hs) = 5.6 feet with a period of 3.2 seconds with the direction of wave propagation parallel to the length of the floating breakwater. ...AM004 As a minimum, a multiplier of 1.67 shall be used to adjust wave height to H1/100 for all concrete floating breakwater internal structural design requirements. Thus, a minimum wave height of 5.6 feet shall be used for general structural design requirements and a minimum wave height of 9.35 feet shall be used for hogging and sagging moments and related structural design requirements.

1.4.2.2 Loading - Construction Related Activities

The concrete floating breakwater design shall include provision for all construction related activities such as handling, transportation, and site

SECTION 01 91 41 Page 4 deployment.

1.4.2.3 Transient Mooring Wind Loading

1.4.2.4 Extreme Wind Loading

The concrete floating breakwater shall be designed for winds blowing perpendicular to the length of the concrete floating breakwater of 123 mph for 3 seconds. Effects of icing may be disregarded as accumulation of ice shall be offset by a corresponding decrease in freeboard.

1.4.2.5 Vertical Live Load Capacity

The uniform live load capacity of the concrete floating breakwater shall not be less than 100 psf. Such loading shall be continuous over the entire deck surface, and alternatively to occur in any combination of unbalanced conditions. The concrete floating breakwater shall be designed to carry a 400-pound point load applied at any point on the breakwater.

1.4.3 Concrete Floating Breakwater Performance

1.4.3.1 Wave Transmission - Installed Position

The concrete floating breakwater shall limit the transmitted wave to no greater than 1 foot on the harbor side in the region of the marina behind the main breakwater as indicated on Drawing C-101 under all incident wave conditions indicated above.

1.7 QUALITY REQUIREMENTS

The concrete floating breakwater will be placed in service in a harsh marine environment at Bar Point Harbor in Ketchikan, Alaska. The corrosion typical of marine environments is present as well as a high number of annual freeze-thaw cycles. The materials selected for use in the concrete floating breakwater shall be such as to provide for a minimum 50-year service life with only minor maintenance. Minor maintenance is defined as maintenance required in the Operations and Maintenance Manual for wearing parts such as connections between concrete floating breakwater segments and connection to marine chains. Acceptance of alternate designs shall be dependent on providing documentation of similar structures, in similar environmental conditions, which have been in service for a time period approaching or exceeding 15 years, with a documented record of minor maintenance. Contractor proposed designs shall include a minimum of three references of owners or operators of facilities where similar concrete floating breakwaters, in similar environmental conditions, have been in service for a minimum of 15 years.

Multiple breakwater units are specified and shall be match-cast to ensure that they may be properly assembled and post-tensioned. If post-tensioning is not accomplished at the precast concrete plant, the precast plant shall be certified by the PCI Plant Certification Program for Category C1 work for casting of concrete floating breakwater modules.

PCI Plant quality control program records shall be available for review.

If multiple units are not post-tensioned at the precast concrete plant the assembly/post-tensioning plan shall be included as part of the professional engineer's stamped design drawings and calculations.

Contractor is required to demonstrate by test results or supporting

SECTION 01 91 41 Page 7 calculations how the concrete floating breakwater articulation joints and chain connections have the durability to meet the design life requirement through the use of corrosion and fatigue resistant material selection, adequate reserve material to offset material loss or proper detailing and maintenance requirements as documented in the Operations and Maintenance Manual.

1.8 TURN OVER REQUIREMENTS

The concrete floating breakwater shall be turned over to the United States Army Corps of Engineers, Alaska District fully assembled and anchored in the correct location. Any field assembly shall be accomplished in compliance with EM 385-1-1 .

1.8.1 As-Built Survey
